The flickering tail light made it real for me. I have a 73 Convertible, darn tail lights and their grounds cause weird issues. Nice looking car. Fun video to watch.
It's a 'Big Body" thing. Over the years I've had 10 of the '71 - '73s and every one of them did the same thing. You can adjust the wiring and change the bulbs over & over trying to get it to stop and it won't take long and one of them will go back out again. 🤦♂The only success I've hade on my current '73 Mach is to put LED bulbs in them. I've had them in there for about 8 months and so far so good. Fingers crossed!! 😁🤞
